Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equation mc025-1.jpg represents the situation, where t is the age of the car in years and r is the rate of depreciation. About how old is Devon’s car? Use a calculator and round your answer to the nearest whole number.

Answers

Answer 1

Answer:

Cost =16000
rate of depreciation = 35%
written down value = 2000
depreciation for one year =16000*35% = 5600
5600*2 = 11200+5600*6\12 = 2000
the car is 2.5 years old. It has been depreciated for 2 whole years and half years.

The complement of 4 heads in the toss of 4 coins is (Please explain)! Thanks!

Exactly one tail

At least one tail

All tails

Three heads

Answers

By using sample space we can say that complement of 4 heads in the toss of 4 coins is at least one tail .

What is sample space ?

set of all possible outcomes experiment is called sample space .

To find compliment of 4 heads we will first find sample space Sample space= S

= { HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH, TTTT }

Given case is 4 heads Say A= { HHHH}

Now we can calculate A complement as

A' = S-A

= { HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH,TTTT }- { HHHH}A'={ HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH,TTTT }

By using sample space we can say that complement of 4 heads in the toss of 4 coins is at least one tail .

Estimate the sum by rounding each mixed number to the nearest half or whole number.8 1/5+ 1 7/16

Answers

You round the 1st number to the nearest whole number which is 8. The second number is rounded to the nearest half.
So it would be 8 + 1 8/16 = 9 1/2.

Write the missing value above the variable. M-9=7

Answers

If you're for the value of "m" then follow these steps to see what the answer is

m - 9 - 7 = ?
? = 0

Now, let's add the number 16 to the sides that you're working with
Here's what I am talking about in case you don't know what I am talking
m - 16 = 0
+ 16
-------
16

So, the value of m is 16 ;
$m=16$

This is basic mathematics.Just practice your addition and subtraction facts in the problem like this

m=16
16-9=7

A line has a rise of 6 and a slope of 1/20. What is the run?

Answers

The slope of a line is a number that represents thedirection and the steepness of the line. Or it is commonly defined as the riseover the run. It is denoted by the letter m. Let’s say that y is the rise and xis the run. A line may be increasing or decreasing just by knowing the slope. Ifthe slope is a negative number, the line is decreasing, and if it is a positivenumber, the line is increasing. Here you have a slope of 1/20 and a rise of 6. Them is equal to 1/20 and y equals 6. So

m = y/x
1/20 = 6 /x
x = 6/(1/20)
x = 120

3/x + 2/y - 4/xy

Answers

This will reqiure cross multiplication. We multiply by crossing the denominators and numerators. This is the solution : -

3/x + 2/y - 4/xy

= 3y+2x/xy - 4/xy                 (xy is common denominator)

=          3xy + 2x - 4
                  xy
